Stopper rod movement, main hydraulic cylinder are connected by fluid pressure line B with secondary hydraulic cylinder, and the end of the auxiliary piston bar of secondary hydraulic cylinder is connected with punching
Head controls auxiliary piston bar by main hydraulic cylinder oil inlet and oil return and moves back and forth drive formed punch punching and revert action.
Under the premise of not changing original mould main structure and Sheet Metal Forming Technology, inclined wedge punch pattern is changed to hydro piercing side
The mechanical energy of press is converted to the fluid pressure energy of main hydraulic cylinder, then fluid pressure energy is converted to mechanical energy by formula, saves energy
Consumption, simultaneously because the flexibility of fluid pressure line B, distribution is more convenient, can satisfy complicated Sheet Metal Forming Technology requirement.
Detailed description of the invention
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is that main hydraulic cylinder and driving mechanism cooperate schematic diagram；
Fig. 3 is the operation schematic diagram of secondary hydraulic cylinder.
Specific embodiment
The present invention is discussed in further detail below with reference to Fig. 1-Fig. 3.
A kind of hydraulic side blow aperture apparatus, including workbench 10 are fixed on workbench 10 to punching part A, on workbench 10
It is provided with main hydraulic cylinder 20, driving mechanism 30 drives the main piston rod 21 of main hydraulic cylinder 20 to move, and main hydraulic cylinder 20 passes through hydraulic
Pipeline B is connected with secondary hydraulic cylinder 40, and the end of the auxiliary piston bar 41 of secondary hydraulic cylinder 40 is connected with formed punch 42, passes through main hydraulic cylinder 20
Oil inlet and oil return control auxiliary piston bar 41 move back and forth and drive 42 punching of formed punch and revert action.Do not changing original mould main body knot
Under the premise of structure and Sheet Metal Forming Technology, inclined wedge punch pattern is changed to hydro piercing mode, the mechanical energy of press is converted to main liquid
The fluid pressure energy of cylinder pressure 20, then fluid pressure energy is converted to mechanical energy, energy consumption is saved, simultaneously because fluid pressure line B's is soft
Soft, distribution is more convenient, can satisfy complicated Sheet Metal Forming Technology requirement.
Preferably, the rodless cavity of the secondary hydraulic cylinder 40 is communicated by fluid pressure line B with the rodless cavity of main hydraulic cylinder 20,
The rod chamber of secondary hydraulic cylinder 40 is communicated with the rod chamber of main hydraulic cylinder 20.When the main piston rod 21 of main hydraulic cylinder 20 is transported to rodless cavity
When dynamic, the hydraulic oil in 20 rodless cavity of main hydraulic cylinder will be entered by fluid pressure line B in the rodless cavity of secondary hydraulic cylinder 40, in turn
It pushes auxiliary piston bar 41 mobile to the rod chamber of secondary hydraulic cylinder 40, drives the formed punch 42 of 41 end of auxiliary piston bar to punching part A
Upper punching, after the completion of punching, the main piston rod 21 of driving mechanism driving main hydraulic cylinder 20 is moved into rod chamber, and hydraulic oil is from pair
The rodless cavity of hydraulic cylinder 40 is back in the rodless cavity of main hydraulic cylinder 20, and auxiliary piston bar 41 is mobile to rodless cavity direction, is driven
42 return of formed punch of 41 end of auxiliary piston bar, to complete puncture motion.
In order to make full use of the energy, the driving mechanism 30 be include that vertical direction is arranged on upper die holder to arrange
Compression bar 31, the main piston rod 21 of main hydraulic cylinder 20 arranges that 31 downlink of compression bar pushes main piston rod 21 perpendicular also for vertical direction
Histogram is to movement.Main piston rod 21 is pushed vertically using the power mechanism driving compression bar 31 of press itself, is not needed separately with a set of
Power unit, the lower end of compression bar 31 can be separate type with the upper end of main piston rod 21 here, both vertical direction cloth
It sets, the pressure of press can be utilized to the greatest extent.
Further, the upper end of the main piston rod 21 is connected with the pressing plate 32 of horizontal direction arrangement, main hydraulic cylinder 20
Two sides are symmetrical arranged there are two nitrogen gas spring 33 arranged in a vertical direction, and the lower end of nitrogen gas spring 33 and workbench 10 are fixed and connected
Connect, upper end is fixedly connected with the lower face of pressing plate 32, the elastic force of nitrogen gas spring 33 driving pressing plate 32 drives main piston rod 21 upward
It is mobile.When pushing, the lower end of compression bar 31 is acted directly on the upper face of pressing plate 32, and when backhaul, there is no need to press to mention
For power, but rely on 20 two sides of main hydraulic cylinder to be symmetrical arranged there are two the elastic force of nitrogen gas spring 33 arranged in a vertical direction to drive
Dynamic pressure plate 32 drives main piston rod 21 to move up, because nitrogen gas spring 33 also can be by during compression bar 31 pushes pressing plate 32
Corresponding compressed energy-storage, when backhaul, nitrogen gas spring 33, which releases energy, to be jacked up pressing plate 32 and moves upwards, and then drives main piston rod
21 move up.
According to punching quantity, position and its angle actually required on punching part A, secondary hydraulic cylinder 40 is provided with multiple groups,
The shaft core direction of auxiliary piston bar 41 is horizontal direction and/or arranges with horizontal direction in angle formula.Production is substantially increased in this way
Efficiency.
The outside of formed punch 42 is equipped with elastic washer 43, and elastic washer 43 is that binder and discharging are played in punching technology
Effect, while the noise of punching generation can also be reduced.
Further, sealing structure, secondary hydraulic cylinder are provided between the inner chamber of cylinder block of main hydraulic cylinder 20 and main piston rod 21
Sealing structure is provided between 40 and auxiliary piston bar 41.
